Cassini-Huygens Arrives Tonight!

Six and a half hours from now an engine will fire on the Cassini-Huygens spacecraft, causing it to make the transition from solar to Saturnian orbit. The craft has taken seven years to get to Saturn, and it's set to provide us with the most spectacular images we've ever seen of the ringed planet, not to mention unprecedented scientific data.

You can watch live NASA TV coverage online starting at 9:30 EDT/6:30 PDT. The engine burn begins just over an hour later, lasts ninety-six minutes, and ends just after midnight (EDT). A PDF is available containing a detailed timeline.
